The turbidity sensor detects water quality by measuring level of turbidity. It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water. As the TTS increases, the liquid turbidity level increases.

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

This thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage that can be read by an analog-to-digital converter (ADC).

Sometimes you need to sense pressure in a damp or caustic environment. And sometimes you need to know the relative changes in pressure as well as the absolute pressure...
